What Drives Savings Variation in Birmingham
Roof orientation is the largest variable — south-facing B17 and B29 rear roofs outperform east-facing B6 or B8 terraces by 15–20%. Urban shading from trees or adjacent properties affects some inner-city B1–B12 addresses. Battery storage is the single biggest lever: shifting self-consumption from 40% to 70% adds £350–£450 annually to savings on a 4kWp system.
Lifetime Savings: The Full 25-Year Picture
A 4kWp + battery install in Birmingham at 2.5% annual electricity price inflation returns approximately £30,000–£38,000 in lifetime savings on a combined cost of £9,900–£12,700. That is a 2.5–3.5x return, tax-free, over the panel warranty period.
